SWING-MTION TRUCK FOR CARS.

Application filed March 2S.

T o all whom if may concer/i:

Be it known that l, (Humala DtNcANsoN Yotixo. of (,ohunlu. in the rount)v ol' Franklin aint-State ofUhio. have invented certain new and u wtul lmpr-'n'ementa in Swing-Motion 'l`rurl;.-.' for Cars; and l lo hereby derlarev the following` to he a full, rlear, and exart leseription of the invention7 such as will enable others skilled in the art to whit-h it appertains to make and use thel :Ix-ame.

My invention relates to an improvementin swing motion truek A foicars, :unl is designed partirularl)v as an improvementon the construction dist-toned in Patent No. S-l-il, granted to ineDecemher 21st, 1905), the ohjert. of the present invention being to dispense with the removable-pins supporting the yokes 'arrying the. holster. alnl mount the yoke on parts integral witlrthe trnrk columns, thus4 strengthening the trueli structure, :unl eliminatingr the liability of :n-eitlent tlue to breakage or tlisplarement of the volufhohling pins.

A further object is to provide :t construetion wherein the upper part ot' the axle boxes` are formed integral with the Hille frames of the trurk. the eellar l or lower parts of the hotes liein r removahle and tletachahly secured to the. upper parts of the boxes.

A further ohjert. is, to provitle a consti-nef, tion, when-hy in the event of breakage of any of the hol ter tspemlinpr parts. the Haiti parta will become loi-keit within thtl shle Traun-s, thus makin;r thetruek safe for ron- 'tinneil servire.

Y Formed in the frame hetween the upper :unl lower arrhes :uni the eolnmn: l. is the hol ter opening. The holster i npporteil :it its entls within the. openingsy in the. two #itle frames, upon the Springs ll. ral-rieti hy the .-pring featl 8, the lat'ter being:r tnonntal upon the lower memher of the hanger yolt'es fl. the vertiral unauherb` of which are suspended from their upper entls on two lugs It), as clearly shown in Fig. 33. These lug4 or A upporth 10. are cast integral with the. rolnmn# l. anil projert into the holster openinf. :unl eat-h lug or Supportis provitletl with two roninlefl hearing snrfaees 10'l as clearly shown in Fig. 2. The two bearing surfacel l0" ou eaeli column, are'lo rated 1n the `-tame horizontal plane ou opposite `:illes of the vertiral renter of their rolnmn. and eurh pair is provitletl with a etnovahle plate l0 shaped to ronform to the top Snrfare of the lugs. nml wein-ett to the latter hy lit-inline it entlav 10" uinler the flanges lO'l. This4 plate is introtlneed or piaeetl entlwise ou the lugs. :unl when in place is hohl against' outwartl displacement h v the ixle arnm of the Yoke. TlJSe plates 10h are tleaignetl to protert the lugs lt);L from wear, :unl l using plates ot' (lith-rentJ thirl' ne ses the height of the. yoke or rather the distant-e het ween 'the upper fare of the lower arrh anni the horizontal member of the yoke ran he adjusted as desired.

The hearing r lugs 10, two for earh upright, memher oi' eaeh yoke. rest'- wjthin the ein-wil wats il 'fot'lnetl in the outer l'art's nl" the, upright inemhers of the lYoke. as shown in Fig'. 3, whieh eat-n' D are loratetl on opposite siete o1' the Ve) tit-al renter ol' said members. so that. normally the yoke will rest on all font' hearing lugs lof. eonsequeutlyeannot .swing exeept when the truek tilts. awhen turning a eurve or when t'oreihly hwun; h t' thtl omlwise movement oll the holster.

Une of the-tentures of m invention is the novel ron trurtion ol the Yoke i) whieh provides for the maximum trenj fth ot' an open hook hanger `yoke, with the minimum amount of mala-rial. This is olitaineil by tn'ovitling an integral lnitlge 9" aeros the opening" ol' the hookrtl shapell hanger memhers as shown in l"i; 2. This hritlg'e is simplj.' a platr or weh integral with the volte fr :unl hrittfing1 or eloriiug the spare u-lween the hooked hapezl etuis of the volte :unl the hotly of the latter.l thus tying the enl'tecl seats. 1? l'ornu'tl in the outer faces of the upof the yoke t) which supports the spring seat S.

The upper face of the lowetvor horizontal i member ot' the yoke, is curved m the arc ol a circle. and t'orms a supportl for the spring seat hi, which latter is enlarged on its under face at its center, which enlargement is provided with a concave reces-.s conforming in shape and size to the convex face of the horizontal member of the yoke. 'l'his spring seat. is a box like structure open at its top and provided at its l'ront and rear with upwardly projecting integral members e, t'orming in ctt'eet columns which latter are embraced or overlapped by the guides b secured to the bolster, and operate to guide the latter in its vertical movements. As the spring seat is mounted to rock on the yoke, and as the bolster guides embrace the upwardly projecting members e of the spring seat, it follows that. any endwise movement of the bolster will be transmitted to the spring seat and either rock the latter on the yoke or canse. the yoke to swing.

Une important. feature of my invention is the construction ol the lower arch, and from an inspection of Figs. 2, I5 and 4, it will be seen that the contour of the upper face thereof is formed by striking arcs from the center ol' the two lugs lll on which each upright member of the yoke is journalcd, the

two curved surfaces l'orming in cll'ect a pocket in which the lower member ot' the yoke moves. By reason oll the two supporting lugs for each upright member ol' the yoke, the path of movement ot' the spring .seat b and yoke t) in swinging, is concentric with the eut-ved surfaces o1' the pocket, and owing to the .shape of the lower arch. the. size of the yokes, and the pro.\'imit ot the lower member of the latter to the pocket in the lower arch, it is apparent. that il one or more lugs 1t), or the yoke should break, the latter would fall into the pocket and thus sustain the parts in position for sal'c service.

if one lug should break', or the yoke. be ruptured and disengaged from one lug, the weight will be transferred to the other lug thus changing the center of gravity of the yoke. and swinging its lower end sidcwise and into contact. with the lower arch. The parts are then locked and rigid. 'the truck under these conditions becomes ol' the rigid typc,and is safe for opcratiomin that il. will be. impossible for the bolster i' to disengage itself from side frame l, on account of the shape ol the carrying arch 3, and the eonstruclion of the engaging surfaces of the spring seal. amt yoke. Any breakage that would let. the lower 'ucmber of the yoke down omo the lower arch, would also lower the engaging surfaces of the spring seal. onto the arch and thus support the spring seat. solidly on the arch.

The cylindrical bearing of the spring seat on the horizontal member of the yoke, as

shown atj in Fig. 4, is of ample area to reduce the wear of parts 8 and 9 to a minimum and bring the lowest point of swinging for hanger `voke t) continguons totower arch 3.

'bile l have shown a hanger with two lug supports at each side, I do not lConfine my invention to such eonstruetion, as the torni ot' arches may be made to conform to any method of supporting, such as one lug center hung, or one lug to the right or left of center.

l'lach side frame l is provided with openings at points as close as possible to the point of loading, to receive the ends of the cross ties l2, which latter are pivotally secured to the side frames, on oppositesides ot' the bolster by pins 13 as shown in Fig. 5. ly this arrangement I provide for tiexibilit v between the side frames and Cross ties without all'ecting the parallelism of the side frames.

The upper lsections 1l of the journal boxes a are cast integral with the side frame, and are provided at their front and rear sides with lugs l5 for the passage of bolts which secure the bottoms` or cellars 16 of the boxes. to the upper parts of the boxes. The journal box tid openings and ribs for .the wedges and brasscs are formed wholly in the upper portion of the boxes, while the lower separable part simply acts as a container or support for the waste and (il.

lt is evident that many slight changes might be resorted to in the relative arrangement ot' parts shown and described without departing from the spirit and scope of my invention: hence l would have it understood that l do not wish to conline myself tothe exact construction and arrangement of parts shown` but,

Having fully described my invention what l claim as new and desire to secure by Lettels-Pat ent, is
